==============================
Jacob Pontusson De la Gardie (Reval, 20 June 1583 - Stockholm, 22 August 1652) was a statesman and a soldier of the Swedish Empire.
(...)
As a young adult, De la Gardie was held prisoner in Poland for four years, together with Carl Gyllenhielm. After being released, De la Gardie took part of the Dutch Revolt as a volunteer.[1] Between 1606 and 1608, De la Gardie served under the Dutch general Maurice of Nassau, Prince of Orange. Impressed with the Dutch way of waging war, De la Gardie began introducing Dutch methods into the Swedish army upon his return to the service of Sweden.
During the Polish-Russian War (1605-1618), Sweden signed an alliance with tsar Vasili IV of Russia in 1609. Sweden promised to send troops to the tsar and gained, in return, the County of Kexholm. De la Gardie was put in command of the Swedish force, which consisted of mostly mercenaries, but Swedish and Finnish soldiers as well. This campaign, which eventually took De la Gardie and his troops all the way to Moscow, is known as the De la Gardie Campaign. It ended with a devastating defeat at the Battle of Klushino in the summer of 1610, from which De la Gardie had to retreat.[1]
Not long thereafter, the Ingrian War between Sweden and Russia was initiated, during which De la Gardie played a significant part militarily. He also claimed that Sweden should take advantage of the on-going turmoil in Russia, later known as the Times of Trouble, and try to place Charles Philip, younger brother of the Swedish king Gustavus Adolphus, on the Russian throne. After some negotiating, these plans were abandoned due to lack of engagement from Gustavus Adolphus and uncertainty on the Russian side.[2]
In 1617, De la Gardie became the chief Swedish negotiator at the Treaty of Stolbovo that ended the Ingrian War, whereby Sweden was able to secure important territorial concessions from Russia, effectively closing off Russia from access to the Baltic Sea.
Between July 1619 and 1622 was Governor of the Swedish Estonia and in 1626 De la Gardie purchased an estate with a medieval castle in Haapsalu, in modern-day Estonia. His time as governor of Estonia was followed by a time as Governor-General of Swedish Livonia 1622-1628.
After 1621, De la Gardie took part in the Polish-Swedish War against his mother's half-brother King Sigismund III of Poland (former king of Sweden) in Livonia, but he was recalled after serving as commander in chief between 1626 and 1628. De la Gardie was an advocate of peace with Poland and acted as one of the Swedish negotiators at the Truce of Stuhmsdorf in 1635.

Prelude:
During Russia's Time of Troubles, Charles IX of Sweden sent an expeditionary corps under Jacob De la Gardie to capture the Russian fortress of Old Ladoga. On hearing about their arrival to Ingria, the Novgorodians asked the king to install one of his sons — Carl Filip or Gustavus Adolphus — as their monarch and on this understanding submitted the city to De la Gardie.
Vasily IV besieged in Moscow by the Tushino gang and driven to despair by the ongoing Polish intervention, then entered an alliance with Charles IX, who was also waging war vs Poland. The tsar promised to cede Korela Fortress to Sweden in recompense for military support against False Dmitry II and the Poles. Thereupon De la Gardie joined his forces with the Russian commander Mikhail Skopin-Shuisky and marched from Novgorod towards Moscow in order to relieve the tsar.
Sweden's involvement into the Russian affairs gave Sigismund III Vasa a pretext to declare war on Russia. The Poles engaged the combined Russo-Swedish forces at Klushino and destroyed most of the Russian force; the Swedish mercenaries taking part in the De la Gardie Campaign (July 1610) surrendered. The battle had serious consequences for Russia, as the tsar was deposed by boyars and the Poles occupied the Kremlin.
Fighting:
In the meantime, Gustavus Adolphus succeeded to the Swedish throne. The young king decided to press his brother's claim to the Russian throne even after the Poles had been expelled from Moscow by a patriotic uprising of 1612 and Mikhail Romanov had been elected a new tsar.
While the Swedish statesmen envisaged the creation of a Trans-Baltic dominion extending northwards to Archangelsk and eastwards to Vologda, De la Gardie and other Swedish soldiers, still holding Novgorod and Ingria, saw the war as a reaction for their forces not receiving payment for their succour during the De la Gardie Campaign.
In 1613 they advanced towards Tikhvin and laid a siege to the city, but were repelled. The Russian counter-offensive failed to regain Novgorod, however. The Russian tsar refused to commit his troops to battle and the war lumbered on until 1614, when the Swedes captured Gdov.
The following year they laid siege to Pskov but Russian generals Morozov and Buturlin held their own until 27 February 1617, when the Treaty of Stolbovo stripped Russia of its access to the Baltic Sea and awarded to Sweden the province of Ingria with the townships of Ivangorod, Jama, Koporye and Noteborg. Novgorod and Gdov were to be restituted to Russia.
As a result of the war, Russia was denied access to the sea for about a century, despite its persistent efforts to reverse the situation.
=====================================
To summ up - Swedish armies never captured Moscow. Nor did this Finnish general.
In the initial part of the Ingrian War - Sweden was not fighting vs Russia, but vs Poland (and her few Russian supporters / traitors).
